This is an activity about scale. Participants will arrange imagery of Earth and many other space objects in order of their size from smallest to largest, their distance from Earth's surface, their temperature from coolest to hottest, and/or their...(View More) age from youngest to oldest. By manipulating these images and discussing their ideas, children and adults represent and confront their own mental models of space and time.(View Less)

This is an activity about image comparison. Learners will analyze and compare images taken by the Solar Dynamics Observatory. They will match four magnetic solar images, or magnetograms, to their corresponding extreme ultraviolet, or EUV, light...(View More) images by studying solar features in the images. At the end, they will recognize that areas of high magnetic activity on the Sun correspond to extreme solar activity.(View Less)

This is an activity that compares the magnetic field of the Earth to the complex magnetic field of the Sun. Using images of the Earth and Sun that have magnets attached in appropriate orientations, learners will use a handheld magnetic field...(View More) detector to observe the magnetic field of the Earth and compare it to that of the Sun, especially in sunspot areas. For each group of students, this activity requires use of a handheld magnetic field detector, such as a Magnaprobe or a similar device, a bar magnet, and ten small disc magnets.(View Less)

This 12-lesson unit includes inquiry-based lessons about the surface features of the Moon and the Earth and how these two worlds formed and continue to evolve. Students participate in real science as they help lunar scientists map the surface of the...(View More) Moon with MoonMappers, an online citizen science project that lets the public analyze real data from NASA's Lunar Reconnaissance Orbiter. The lessons in this unit follow the 5E instructional model. Includes an overview of citizen science, glossary of lunar feature vocabulary, alignment to NGSS and NSES, and featured links. Each of the lessons addresses different topics and can be used together as a unit, or independently.(View Less)
